先ず、図１に示すように、前後方向Ｄ１及び左右方向Ｄ３が水平面に平行の位置関係となるように容器本体２を配置させる。次に、複数枚の基板Ｗを基板支持板状部５の板部５１の凸部５１１、５１２にそれぞれ載置する。Next, in the above-mentioned substrate storage container 1, the operation when the substrate W is stored in the substrate storage space 27 and the container body opening 21 is closed by the lid 3 will be described. FIG. 8 is a schematic view showing how the substrate W is inserted into the V-shaped groove 703 of the front retainer substrate receiving portion 73 of the substrate storage container 1 according to the embodiment of the present invention.
First, as shown in FIG. 1, the container body 2 is arranged so that the front-rear direction D1 and the left-right direction D3 are in a positional relationship parallel to the horizontal plane. Next, a plurality of substrates W are placed on the convex portions 511 and 512 of the plate portion 51 of the substrate support plate-shaped portion 5, respectively.

次に、蓋体３を容器本体開口部２１へ接近させてゆき、フロントリテーナ７のフロントリテーナ基板受け部７３に当接させる。そして、図８に示すように、更に蓋体３を容器本体開口部２１へ接近させてゆくと、基板Ｗの縁部の裏面の端縁は、上下方向Ｄ２へ長く形成された下側基板誘い込み傾斜面７３３に対向しているため、下側基板誘い込み傾斜面７３３に当接し、図８において矢印で示す方向へ摺動し導かれる。そして、下側傾斜面７３１に至ると、基板Ｗの縁部の裏面の端縁は、下側傾斜面７３１に当接し、下側傾斜面７３１に対して摺動してせり上がる。同様に、奥側端縁支持部６０においても、基板Ｗが図示しない下側傾斜面６１１に至ると、基板Ｗの縁部の裏面の端縁は、奥側端縁支持部６０の下側傾斜面６１１に当接し、下側傾斜面６１１に対して摺動してせり上がる。 Next, the lid 3 is brought closer to the container body opening 21 and brought into contact with the front retainer substrate receiving portion 73 of the front retainer 7. Then, as shown in FIG. 8, when the lid 3 is further brought closer to the container body opening 21, the edge of the back surface of the edge portion of the substrate W is attracted to the lower substrate formed long in the vertical direction D2. Since it faces the inclined surface 733, it comes into contact with the lower substrate invitation inclined surface 733 and is guided by sliding in the direction indicated by the arrow in FIG. Then, when the lower inclined surface 731 is reached, the edge of the back surface of the edge portion of the substrate W comes into contact with the lower inclined surface 731 and slides up with respect to the lower inclined surface 731. Similarly, in the back edge support portion 60, when the substrate W reaches the lower inclined surface 611 (not shown), the edge of the back surface of the edge portion of the substrate W is inclined downward of the back edge support portion 60. It abuts on the surface 611 and slides up with respect to the lower inclined surface 611.

そして、基板ＷがＶ字状溝７０３の頂点の位置に至ったときに、基板Ｗの裏面の端縁、表面の端縁が、それぞれ下側傾斜面７３１、上側傾斜面７３２に当接して、基板Ｗの縁部がＶ字状溝７０３に支持される。同様に、基板Ｗの裏面の端縁、表面の端縁は、奥側端縁支持部６０の下側傾斜面６１１、上側傾斜面６１２に当接して奥側端縁支持部６０に支持される。 Then, when the substrate W reaches the position of the apex of the V-shaped groove 703, the edge of the back surface and the edge of the front surface of the substrate W come into contact with the lower inclined surface 731 and the upper inclined surface 732, respectively. The edge of the substrate W is supported by the V-shaped groove 703. Similarly, the back edge and the front edge of the substrate W abut on the lower inclined surface 611 and the upper inclined surface 612 of the back edge support portion 60 and are supported by the back edge support portion 60. ..

上記構成の本実施形態に係る基板収納容器１によれば、以下のような効果を得ることができる。
前述のように、基板収納容器１は、一端部に容器本体開口部２１が形成された開口周縁部２８を有し、他端部が閉塞された筒状の壁部２０を備え、壁部２０の内面によって、複数の基板Ｗを収納可能であり容器本体開口部２１に連通する基板収納空間２７が形成された容器本体２と、容器本体開口部２１に対して着脱可能であり、容器本体開口部２１を閉塞可能な蓋体３と、基板収納空間２７内において対をなすように配置され、蓋体３によって容器本体開口部２１が閉塞されていないときに、複数の基板Ｗのうちの隣接する基板Ｗ同士を所定の間隔で離間させて並列させた状態で、複数の基板Ｗの縁部を支持可能な側方基板支持部としての基板支持板状部５と、蓋体３によって容器本体開口部２１が閉塞されているときに、基板収納空間２７に対向する蓋体３の部分に配置されて、複数の基板Ｗの縁部を支持可能な蓋体側基板支持部としてのフロントリテーナ７と、基板収納空間２７内においてフロントリテーナ７と対をなすように配置され、複数の基板Ｗの縁部を支持可能であり、蓋体３によって容器本体開口部２１が閉塞されているときにフロントリテーナ７と協働して、複数の基板Ｗを支持可能な奥側基板支持部６と、を備えている。
フロントリテーナ７は、基板Ｗに直接当接して基板Ｗを支持する蓋体側基板受け部としてのフロントリテーナ基板受け部７３と、フロントリテーナ基板受け部７３を支持する蓋体側脚部としての脚部７２と、を備えている。
フロントリテーナ基板受け部７３は、基板収納空間２７の中心から離間するように傾斜して延びる下側傾斜面７３１と、基板収納空間２７の中心に接近するように、下側傾斜面７３１の上端部から傾斜して延びる上側傾斜面７３２と、下側傾斜面７３１の下端部に接続され、下側傾斜面７３１の傾斜よりも、複数の基板Ｗが並列された並列方向に一致する上下方向Ｄ２とのなす角ａが小さく傾斜する下側基板誘い込み傾斜面７３３と、上側傾斜面７３２の上端部に接続され、上側傾斜面７３２の傾斜よりも上下方向Ｄ２とのなす角ｂが小さく傾斜する上側基板誘い込み傾斜面７３４と、を有している。
蓋体３によって容器本体開口部２１が閉塞されているときに、下側傾斜面７３１及び上側傾斜面７３２は、基板Ｗに当接し、下側傾斜面７３１及び上側傾斜面７３２により形成されるＶ字状溝７０３において基板Ｗを支持する。
蓋体３によって容器本体開口部２１が閉塞されているときのＶ字状溝７０３が延びる方向において、容器本体開口部２１の中央に近づくにつれて下側基板誘い込み傾斜面７３３の上下方向Ｄ２の長さは長くなる。According to the substrate storage container 1 according to the present embodiment having the above configuration, the following effects can be obtained.
As described above, the substrate storage container 1 has an opening peripheral edge portion 28 having a container body opening portion 21 formed at one end thereof, and has a tubular wall portion 20 having a closed end end portion, and the wall portion 20 is provided. A plurality of substrates W can be stored by the inner surface of the container, and the container body 2 having a substrate storage space 27 communicating with the container body opening 21 and the container body opening 21 can be attached to and detached from the container body opening. The lid 3 capable of closing the portion 21 is arranged so as to form a pair in the substrate storage space 27, and when the container body opening 21 is not closed by the lid 3, the portions 21 are adjacent to each other among the plurality of substrates W. A container body is provided by a substrate support plate-shaped portion 5 as a side substrate support portion capable of supporting the edges of a plurality of substrates W and a lid 3 in a state where the substrates W to be supported are separated from each other at a predetermined interval and arranged in parallel. When the opening 21 is closed, the front retainer 7 is arranged in the portion of the lid 3 facing the substrate storage space 27 and can support the edges of the plurality of substrates W as the lid side substrate support. , The front retainer is arranged so as to be paired with the front retainer 7 in the substrate storage space 27, can support the edges of a plurality of substrates W, and is the front retainer when the container body opening 21 is closed by the lid 3. In cooperation with 7, the back side substrate support portion 6 capable of supporting a plurality of substrates W is provided.
The front retainer 7 has a front retainer substrate receiving portion 73 as a lid side substrate receiving portion that directly contacts the substrate W and supports the substrate W, and a leg portion 72 as a lid side leg portion that supports the front retainer substrate receiving portion 73. And have.
The front retainer board receiving portion 73 has a lower inclined surface 731 that extends so as to be separated from the center of the board storage space 27, and an upper end portion of the lower inclined surface 731 so as to approach the center of the board storage space 27. An upper inclined surface 732 extending from the inclined surface 732 and a vertical direction D2 connected to the lower end portion of the lower inclined surface 731 and having a plurality of substrates W parallel to each other in a parallel direction rather than the inclination of the lower inclined surface 731. The upper substrate which is connected to the upper end portion of the upper inclined surface 732 and the lower substrate invitation inclined surface 733 where the angle a formed by the slope a is slightly inclined, and the angle b formed by the vertical direction D2 is smaller than the inclination of the upper inclined surface 732. It has an inviting inclined surface 734 and.
When the container body opening 21 is closed by the lid 3, the lower inclined surface 731 and the upper inclined surface 732 come into contact with the substrate W, and the V formed by the lower inclined surface 731 and the upper inclined surface 732. The substrate W is supported by the character groove 703.
In the direction in which the V-shaped groove 703 extends when the container body opening 21 is closed by the lid 3, the length of the lower substrate inviting inclined surface 733 in the vertical direction D2 as it approaches the center of the container body opening 21. Becomes longer.

上記構成により、下方向Ｄ２２へ下側基板誘い込み傾斜面７３３が拡大される。これにより、蓋体３を閉塞させるときに、基板Ｗの縁部の裏面の端縁が下側基板誘い込み傾斜面７３３に当接しやすくなる。この結果、蓋体３を下側基板誘い込み傾斜面７３３を介して、容易に下側傾斜面７３１に当接する状態とすることが可能となり、確実にＶ字状溝７０３へ導くことが可能となる。これにより、フロントリテーナ７において基板Ｗの誘い込み不良、即ち、隣接する複数のフロントリテーナ基板受け部７３間に基板Ｗが入り込んで基板外れの状態となることを軽減可能である。従って、手動で蓋体３を閉める際にも、基板Ｗの誘い込み不良を気にする必要がなくなり、作業性が向上する。 With the above configuration, the lower substrate invitation inclined surface 733 is expanded in the downward direction D22. As a result, when the lid 3 is closed, the edge of the back surface of the edge portion of the substrate W is likely to come into contact with the lower substrate invitation inclined surface 733. As a result, the lid 3 can be easily brought into contact with the lower inclined surface 731 via the lower substrate invitation inclined surface 733, and can be reliably led to the V-shaped groove 703. .. As a result, it is possible to reduce the failure to attract the substrate W in the front retainer 7, that is, the substrate W entering between the plurality of adjacent front retainer substrate receiving portions 73 and causing the substrate to come off. Therefore, even when the lid 3 is manually closed, it is not necessary to worry about the defective invitation of the substrate W, and the workability is improved.

また、フロントリテーナ基板受け部７３は、容器本体２の一端部から他端部へ向う方向（前方向Ｄ１１）である背面視で見たときに平行四辺形状を有している。上記構成により、上下方向Ｄ２において隣接するＶ字状溝７０３とＶ字状溝７０３との間隔を広げずに、下方向Ｄ２２へ下側基板誘い込み傾斜面７３３を拡大することが可能となる。従って、蓋体３によって容器本体開口部２１が閉塞されているときに、Ｖ字状溝７０３において支持される基板Ｗの位置を、基板誘い込み傾斜面７３３を拡大しない従来の構成と同様の位置とすることが可能となる。 Further, the front retainer substrate receiving portion 73 has a parallel quadrilateral shape when viewed from the rear, which is a direction from one end to the other end of the container body 2 (front direction D11). With the above configuration, it is possible to expand the lower substrate invitation inclined surface 733 in the downward direction D22 without widening the distance between the adjacent V-shaped grooves 703 and the V-shaped groove 703 in the vertical direction D2. Therefore, when the container body opening 21 is closed by the lid 3, the position of the substrate W supported by the V-shaped groove 703 is the same as that of the conventional configuration in which the substrate invitation inclined surface 733 is not enlarged. It becomes possible to do.
